The oven cleaner that dissolves baked-on grease, without caustic soda.
Most oven cleaners work by burning through grease with caustic soda: the fumes, the gloves, the warning label. Oven-Pro is a non-caustic oven cleaner built on modified citrus extracts and a plant-derived solvent-surfactant that gets underneath the grease and lifts it off.
- Non-caustic: no sodium hydroxide, no caustic soda
- Modified citrus extracts plus a plant-derived solvent-surfactant
- For oven interiors, glass doors, racks, trays, grills, hobs and BBQs
- Works in 30–60 minutes, wipes off with warm water
- Shifts the grease or it's free
- Free next-day delivery: order by 3pm, ships today

Why baked-on grease won't wipe off, and how Oven-Pro takes it apart
Grease that's been heated again and again stops being grease. Every time the oven runs, splashes of fat oxidise and cross-link into a hard, varnish-like film that water and washing-up liquid just slide over.
Caustic cleaners attack that film chemically. Sodium hydroxide turns fat into soap, and it works, but it's the reason most oven cleaners carry a corrosive warning, sting your eyes and leave the kitchen smelling for hours.
Oven-Pro takes a different route. It's built on a plant-derived solvent-surfactant made from natural oils using Nobel Prize-winning chemistry, paired with citrus extracts we modify to go after baked-on fats. It wets the surface like a detergent, then works like a solvent once it's in, softening the polymerised grease from underneath so it lets go of the enamel.
It spreads instead of beading
The surfactant side drops surface tension, so Oven-Pro flattens out across glazed grease instead of sitting on top of it.
It gets under the grease
The solvent side dissolves into the polymerised fat and works down to the enamel, softening it from the inside out.
It lets go and wipes away
Loosened grease is held in suspension, so a cloth and warm water take it off. No chiselling, no caustic residue to rinse out.

Where it works, and where it won't
We'd rather tell you now than sell you a bottle for a job it can't do.
- Enamel oven interiors, base and walls
- Oven door glass, inside and out
- Shelves, racks, roasting tins and trays
- Grill pans, hobs and extractor filters
- BBQ grates and range-cooker surrounds
- Air-fryer baskets and drawers (not the element)
- Catalytic "self-cleaning" liners
- Heating elements, fan housings and rubber door seals
- Painted trims and soft plastics: test a hidden spot first
- Thick black carbon: it softens it, but you'll still need a scraper

Four steps, about an hour, mostly waiting
No scrubbing marathon. Most of the time is Oven-Pro working while you do something else.
Warm and wet
Take the racks out. Mist the inside with water, then warm the oven to about 70°C and switch it off.
About 10 minutesBrush it on
Cover the greasy areas with an even layer using a long-bristled brush. Keep it off rubber seals and the heating elements.
About 5 minutesLet it work
Leave it to soak in. Light soiling needs about 30 minutes; heavy, baked-on grease up to an hour.
30–60 minutesWipe and rinse
Wipe off with a cloth and warm water. Burnt-in carbon may need a scouring pad or scraper. Rinse, dry, done.
About 10 minutes

Oven cleaner questions, answered
Is Oven-Pro caustic?
No. It contains no sodium hydroxide (caustic soda), which is the active in most supermarket oven cleaners. It works with modified citrus extracts and a plant-derived solvent-surfactant instead.
Is oven cleaner toxic?
Caustic oven cleaners are corrosive: they can cause severe skin burns and eye damage, which is why they carry a danger label. Oven-Pro is non-caustic, but it's still a cleaning chemical, so wear gloves, ventilate the room and keep it away from children and pets.
How long do you leave oven cleaner on?
With Oven-Pro, about 30 minutes for light soiling and up to an hour for heavy, baked-on grease. Warming the oven to around 70°C first and then switching it off helps it work faster.
What's the best oven cleaner for a very dirty oven?
One that can get under polymerised grease, not just the surface. Oven-Pro's solvent-surfactant action does that without caustic soda. On thick black carbon, expect to do a second coat and use a scraper.
Can I use it on the oven glass door?
Yes, inside and out. Brush it on, leave it, then wipe off with warm water. It's one of the jobs it does best.
How do I clean oven racks with it?
Lay the racks on old newspaper or in the bath on a towel, brush Oven-Pro over them, leave 30–60 minutes, then scrub with a non-scratch pad and rinse.
Can I use it in a self-cleaning oven?
Not on catalytic liners: those rough, self-cleaning panels shouldn't have any cleaner on them. On pyrolytic ovens, run the cleaning cycle for the cavity and use Oven-Pro on the door glass and racks.
Can I use oven cleaner on an air fryer?
On the removable basket and drawer, yes. Rinse thoroughly afterwards. Never apply it to the heating element, and test non-stick coatings on a small area first.
When can I cook after cleaning?
As soon as it's rinsed off and dry. Run the oven empty for ten minutes first to drive off any moisture.
Will the kitchen smell afterwards?
It smells of citrus while you're using it. There's no caustic soda, so no burnt-chemical smell when you next turn the oven on, as long as you've rinsed it off.
What's the difference between the 1L and 5L?
Same formula. The 1L does one oven properly with plenty to spare. The 5L is for the whole kitchen, BBQs, landlords and cleaners, and works out at £8.00 a litre.
When will it arrive?
Order by 3pm Monday to Friday and it's dispatched the same day from our Glasgow unit, delivered next working day, free, UK mainland.
What if it doesn't work?
Shifts it or it's free: send us a photo and your order number within 30 days and we'll refund you.
